270923-41-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 270923-41-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,0,9,2 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 270923-41:
(8*2)+(7*7)+(6*0)+(5*9)+(4*2)+(3*3)+(2*4)+(1*1)=136
136 % 10 = 6
So 270923-41-6 is a valid CAS Registry Number.
